Americans consume between two to three pounds of sugar every week. The sugar is being processed in so many foods we eat. These foods are not just sweets. Sugar in large quantities can be found in peanut butter, mayonnaise, bread, ketchup and many other categorically non-sweets products.

Now lets get to the question: Why is Refined Sugar bad for you?

Refined Sugar is bad for you because it raises the insulin level in your blood.

Raised blood insulin levels depress the immune system. If your immune system is depressed then your ability to fight disease is weakened.

Raised blood insulin levels can cause weight gain. Insulin promotes the storage of fat; so, when you eat foods high in refined sugar, you increase fat storage. Obviously, the result is rapid weight gain.

Refined Sugar contains no vitamins or minerals so in order for sugar to be metabolized it must draw on the bodys reserve of vitamins and minerals. When these reserves are depleted, metabolization of cholesterol and fatty acid is impeded, contributing to higher blood serum triglycerides, cholesterol, promoting obesity due to higher fatty acid storage around organs.
